What headphone amp to use with Sennheiser HD800?


I just bought the new Sennheiser HD800 headphones and I would like feedback from other HD800 owners. Which headphone amps have you used with the HD800's and which they selected and why? I live in a very remote area and I am about 300-400 miles away from the closest high end audio dealer. Your suggestions and comments would greatly be appreciated to help me in choosing a headphone amp for these incredible headphones.

I use the Bada hybrid headphone amp with the Sennheiser HD600s. The Bada is exceptionally neutral, dynamic and realistic and responds quite well to tube rolling. While the stock Chinese 6SN7s in the Bada are surprisingly good, NOS RCAs and Sylvanias are magical.
You cant go wrong with the HA-160D!
you can also find lots of positive feedback about it when paired to the HD800's.
A Ray Samuels B52 is a fine match-up. But realize that the 800s can be bright and clinical with some CDs with any amp.
I think tube amps are best for them.
A solid state amp such as the Burson does a good job with them.
Generally, with sennheiser line.
You should look at Head-fi.org for more info. I use a Bottlehead Crack with great result with my HD650. I know they are not 800 but its all i can afford. Anyway i have try some SS amps and for sheer musicality tubes are better. I havent tried the HA-160D but its a very good dac/amp from what people are saying. With SS my 650 sounded bright and digital, but when i tried the BH Crack, it was music like it meant to be.
